I'm currently swapping out a SRAM S300 crankset (external GXP bottom bracket) to a Sugino RD4 (JIS square taper bottom bracket) on my single speed bike and hoping to get some advice from the wrenches here.
I've swapped out both types a few times and it's a pretty straighforward process, but I'm more familiar with external bottom bracket systems and do have a few questions about where to apply grease, anti-seize compound or thread locker on the BB and chainring bolts since I've never installed a new square tapered BB or chainring from scratch.
Below, listing the components, can anyone tell me if I am using the correct methods?:
BB to BB shell interface: Assuming grease on all threads here is fine (both frame and BB are aluminum)
Left BB cup (non-drive side) to main BB interface: Should I use grease, anti-seize compound or nothing? The cup simply slides over the main BB unit, no threading.
Crank arms to spindle interface: From what I understand, I should use nothing here as grease will cause slipping problems
Axle bolt threads (bolting into the spindle): Should I use grease, anti-seize compound or thread locker? (I believe the spindle and bolts are CroMo steel)
Chainring nuts (surface interfacing with the chainrings): Nothing
Chainring bolt threads: Loctite 243, no grease
Referring the product manuals and online info, most tutorials don't seem to specify best practices. Thanks in advance.
